将微型加速度数据记录仪安装在鲤鱼下颌骨上，以远程识别摄食行为。研究了加速度信号能否区分食品的数量和质量。由连续小波变换确定的突波加速度计算的下颌骨行程的频率和幅度在喂食期较非喂食期明显增加。当鱼被喂食一种食物时，平均+/- s.e为187.3 +/- 38.2秒，当鱼被喂食多种食物时，平均+/- s.e为419.3 +/- 28.6秒，这些特征的运动模式保持不变。然而，根据摄食事件持续时间计算的优势周期和幅度在两种饵料之间没有显著差异。涌动加速度检测出的喂养事件平均+/- s.e为89.8 +/- 13.5%，误检率平均+/- s.e为25.9 +/- 10.9%。结果表明，下颌骨加速度测量方法可用于检测和记录采用类似鲤鱼吸食方式的鱼类的摄食事件。
Miniaturized acceleration data loggers were attached to the lower mandible of common carp Cyprinus carpio to remotely identify feeding behaviour. Whether the acceleration signal could distinguish the quantity and quality of food was also investigated. The frequency and amplitude of the lower mandible stroke, calculated from surging acceleration determined by continuous wavelet transformation, significantly increased during the feeding period compared to that during the non-feeding period. These characteristic movement patterns were maintained for mean +/- s.e. 187.3 +/- 38.2 s when the fish were fed a single item of food and for mean +/- s.e. 419.3 +/- 28.6 s when they consumed multiple items. The dominant cycle and amplitude calculated according to feeding event duration, however, did not differ significantly between the two types of diets the fish consumed. Surging acceleration could detect mean +/- s.e. 89.8 +/- 13.5% of feeding events, although the false detection rate was mean +/- s.e. 25.9 +/- 10.9%. The results indicate that the mandible acceleration measurement method could be utilized to detect and record the feeding events in fishes that use a suction feeding mode similar to C. carpio.
